Contact for electrically connecting a first member and a second member using spring part

Abstract

The present invention provides a contact with low impedance even in a high frequency band. The contact ( 1 ) includes a base part ( 3 ), a contact part ( 5 ), and a spring part ( 7 ). The spring part ( 7 ) is elastically deformed to bias the contact part ( 5 ) in the x-axis positive direction and the z-axis positive direction. The contact part ( 5 ) includes a sliding part ( 23 A) oriented in the x-axis positive direction. The base part ( 3 ) includes a part to be slided ( 14 ) oriented in the x-axis negative direction. The contact part ( 5 ) is biased in the x-axis positive direction by the spring part ( 7 ), so that the sliding part ( 23 A) is in pressure contact with the part to be slided ( 14 ). The contact part ( 5 ) is configured to be slidable in the z-axis direction relative to the base part ( 3 ) while maintaining a state in which the sliding part ( 23 A) is in pressure contact with the part to be slided ( 14 ).
